说明：  多项式曲线拟合其中, x, y为已知数据点向量, 分别表示横,纵坐标, m为拟合多项式的次数, 结果返回m次拟合多项式系数, 从高次到低次存放在向量p中. (Polynomial curve fitting where, x, y as the vector of known data points, respectively, horizontal and vertical coordinates, m is the number of polynomial fitting, the results of m-fit polynomial coefficients returned from higher to Low times stored in the vector p,.)

用于坐标转换 空间球形极坐标转化为空间直角三维坐标(For spherical polar coordinates space coordinate conversion into rectangular space three-dimensional coordinate)

将Quaternion四元素坐标系转换为一般的欧拉角坐标系，避免采用反三角函数导致的值域限制问题。参数xi为搜索的精度，对于每个欧拉角可以分别设定，xi越小，搜索越精确。(Quaternion quaternion coordinate system will be converted to general Euler angle coordinate system, avoiding the use of inverse trigonometric functions due to range limitations. The accuracy of the search parameter xi, for each Euler angle can be set separately, xi smaller, more accurate search.)
